DOOR-HANDLING MECHANISM.

1 b all whom it may concern:

Be it known that 1, CHARLES V. Mclx'rmr, a citizen. of the United States of America, residing in the city, county, aml State of New York, have invented certain new and useful Improvements in Door Handling Mechanism, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My present invention relates to door-handling mechanism and particularly to mechanism for manipulating the doors of horizontal retort coke ovens. The general object of my invention is to provide improved means for the general purpose described and the particular object of my invention is to I provide a' simple and effective. mechanism for manipulating coke oven doors characterized by a certain flexibility in operation which minimizes any tendency of the parts to jam or bind but adapted to insure the positive and accurate return of the doors to their normal sealing positions, notwithstanding such warping of the doors and coke oven structure as may be expected to occur in normal operation; a further specific object of the invention is to provide a door handling carriage adapted to run along track rails located in front of the oven structure and above the discharge bench and to take up a relatively small amount of space.

,The various features of novelty which characterize mv invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and the advantages possessed by it, referenceshould be had to the accompanyin drawings and descriptive matter, in which have illustrated and described a preferred embodiment of my invention.

Of the drawings:

Figure 1 is a front elevation of a portion of a coke oven provided with my improved door-handling mechanism;

Fig. 2 is a partial section taken on the line 2-2 of Fig. 1;,

Fig. 8 and Fig. 4 are views taken similarly to Fig. 2, illustrating different positions of apparatus shown in Fig. 2; and Fig. 5 is also a view taken similarly to Fig. :2 but showing a portion only of the apparatus shown in Fig. 2 and with parts in different relative positions.

In the drawings, A represents the coke oven structure; A one of the doorways therein. B represents the door normally closing the doorway A and is formed, as shown, with a metallicframework, and a body portion B of firebrick or other refractory material. At its upper end each door is formed with a pocket or recess F adapted to be entered by the hook or door-engaging end of the door-handling leverG hereinafter described. Adjacent its lower end, the door frame is formed with a central rib or projection B for a purpose hereinafter described.

The door-handling mechanism is mounted on a carriage C, having lower flanged wheels C running on a track rail D mounted on the oven bench A. The carriage C is in guided connection at its upper end with asuspended track rail D by means of guide rolls or wheels C of which, in the construction shown, there are four, arranged in two opposed pairs. The wheels C are journaled on an equalizer C which is pivotally connected by the stud C to the upper end of the frame of the carriage C. The carriage C supports an oscillating door-handling elcment E, provided, adjacent its lower ends, with trunnions E mounted in bearings (1 formed on the body of the carriage C. The axis of the trunnions E is horizontal and parallel to the.planes of the doors to be handled. The member is provided at its upper end, with a gear segment E the teeth of which are in mesh with a gear F carried by a shaft F journaled in bearings C provided on the frame of the carriage C. The shaft F is connected by beveled gears F,

the shaft section F beveled gears F shaft through a suitable controller m, mounted on the carriage C. The upper portion of the member E is made hollow and has journaled therein the. door-engaging lever G, which is mounted on the fulcrum stud or shaft E carried by the member E and having its axis parallel to the axis of the trunnions E. The. lever G is advantageously provided at its door-engaging end with an adjustable doorengaging block G through which the lever G engages the surface B ofthe wall of the pobket B of the door being manipulated.

The outer or. front end of the lever G connected by a link G to a crank arm G carried by a shaft Gr which is journaled in the member E and has secured to it a wormwheel G which is in mesh with the worm G carried by a shaft G passing through one of the trunnions E which is made hollow for the purpose. A clutch H forms a means for connecting and-disconnecting the shaft G to a shaft 1. The latter is connected by beveled gears I, shaft 1*, and beveled gears I to a shaft I. The latter is connected through speed-reducing gearing l to the in mesh with the beveled gear J 2 carried by. 'a shaft J which also carries a worm 111 mesh with a wormwhcel K; The la-tteris secured to a. shaft which also has secured to it a: spur gear K in mesh with a, spur gear L secured to' one end of a crank shaft L journalcd in the frame of the carriage C and located below the member E. The crank port-ion of the crank shaft. L is provided with aroller L? adapted to engage the raised portion B of the ;coke oven door being handled under certain conditions as hereinafter explained. The wheels Care secured to shafts or spindles which carry bevel gears (3 and arccon'nected together by gears in mesh with the gears C -and carried by a shaft 0. The latter also has secured to it a beveled gear 0 through which the shaft 0 is connected to a shaft P.- The latter is mnnee-ted by bevel gears to a wor mwheel Q in mesh with a Worm carried by the shaft of a motor M the movements of which are regulated by a suitable controller m" VVit-h the construction described, it will be observed that the controllers m, an and m and the two clutch-actuating levers H and H are located in com'enlent proximity to one another, so that a single attendant may along the track rails D and D into the posltion in which the door engaging end of the lever (.i' may be moved into the pocket B of the door to be operated on. The lever G is moved into the pocket B by operating the 1notor M to swing the member E from the position shown in F ig. 5 into the position shown in Fig. 2. The controller m and clutch lever H are next manipulated to cause the motor M to tilt the lever G from position shown in Fig. 2 into the position.

shown in Fig. 4:. This transfers the weight of the door from the doorway of the oven structure to the carriage C. After this, the

controller m is again manipulated to swing the member E from the position shown in Fig. 2 to that shown in Fig. 3. Itshould be explained that advantageously the partsare so proportional and adjusted that the block G of lever G engages the wall B of the pocket B at a point approximately straight above the. center of gravity of the door. in consequence, the door tends to move in parallelism with itself, as it is swung fronrthe position shown inFig. 1 into the position shown in Fig. 3, In'Figi. '3 the door is clear of the coke oven structure proper and may be moved transversely of the doorway to which it pertains by the carriage C, as the latter runs along the rails D andD The door is returned into place by me" tions which are the reverse of those described for movmg it out of place. Should the door stick in the doorway in the general position indicated in Fig. 4, when it is attempted to return the door, this "dilficulty may be overcome by a suitable rotation-of the crank shaft L brought about by the manipulation of the controller. m, and clutch lever H. For this purpose; the crank shaft L is swungfrom its normal position shown in Fig. 3 to first bring the roller L on the crank shaft L into engagement with the door portion B and then, as the rotation of the crank shaft continues, to ram the lower portion of the door-back into its proper place in the doorway.

Among the obviousadvantages of the con structionillustrated are its comparative sim;

plicity and positiveness of action, coupled witlrthe facts that the door-handling mechanism proper is not apt to jam orbind in operation. and may be readily adjusted and manipulated toproperly engage and disengage that door handled by it, notwithstanding any ordinary warping of the latter or of the oven structure. The carriage construction employed is desirable in that it con:-

prises convenient and eflective power'means for effecting the movements of itself and the door manipulating instrumentalities carried by it, tivel the best forms of my invention now known handling carriage adapted to me, it will 'be apparent to those skilled in the art that changes can of my invention without departing from its spirit and some features can be chan ed 'without a corresponding change of ot er features.
